“Above all, do not lose your desire to walk.”

"Be humble. Be teachable. The universe is bigger than your view of the universe. There's always room for a new idea. Humility is necessary for growth."

Nice diagram, though one of the points of string theory is that the list would stop there

"The best that most of us can hope to achieve in physics is simply to misunderstand at a deeper level."

- Wolfgang Pauli

[Nirmalya Kajuri @Kaju_Nut]

Pauli once told von Neumann the result of a difficult physical problem and how he had arrived at it. Von Neumann replied that the same result could be derived from just one axiom.

Pauli responded, 'Herr von Neumann! If physics could be done with axioms, you'd be a great physicist!'

(From Jagdish Mehra's obituary of Richard Feynman)

[Dr. Yu-Dai Tsai @YuDai_Tsai]

People love to say, “We need to encourage young people to try, fail, and learn.”

But in practice, they do the opposite.

When was the last time you saw someone genuinely celebrate failure?

Everyone is obsessed with prodigies. I side with the people who fail, and keep trying.

This letter from an 8-year-old reader made my day.

Plato is my friend — Aristotle is my friend — but my greatest friend is truth.

For the nerds out there looking for a deep dive, here is Kazanas' paper: https://t.co/uEpzvp9kKt

And here is Guth's: https://t.co/QjMhyYMTw2

[Deivon Drago @DeivonDrago]

This sort of thing was not just limited to Kazanas. Starobinsky (1980) and Sato (1981) had related work in the same window, and Gliner had even earlier precursors in 1965.

Guth’s publication had the most full-fledged development of the theory, and the monopole + flatness analysis led to it becoming canonical.

Unfair, but sadly there are many papers out there to keep track of.

[Nirmalya Kajuri @Kaju_Nut]

Totally new to me. I knew about Starobinsky's prior work, but it looks like Kazanas may have been the first to propose inflation as a solution to a problem with the hot big bang model.

[Edgar Shaghoulian @eshaghoulian]

Today in "I got shafted because I wasn't as famous as the other guy": Demos Kazanas, the first to propose inflation to solve the homogeneity problem.

Inflation is usually credited to Alan Guth, with important follow-up work by Andre Linde, and Paul Steinhardt & Andy Albrecht.

An expert is someone who knows some of the worst mistakes that can be made in his subject, and how to avoid them.

[Prof. Feynman @ProfFeynman]

It requires a much higher degree of imagination to understand the electromagnetic field than to understand invisible angels.

"If people do not believe that mathematics is simple, it is only because they do not realize how complicated life is."

-- John von Neumann (1903 - 1957)

Understand. Don't memorize.
Learn principles, not formulas.

I'm still unreasonably proud of this paragraph.

[Will Kinney @WKCosmo]

Let me tell you a little bit about my second book, and how it relates to my first book. 1/
